Transient model of the three-phase cage asynchronous machine with saturation and space harmonics effects

Three‐phase induction machines are excessively used and their control has been widely developed. The machine model often used in the control system is the linear 2‐axes d–q machine equations. There is a need for improved methods of analysing the dynamic behaviour to check the validity of the control system. We propose a real three‐phase model including space harmonics effects by Fourier analysis of the air‐gap induction and taking into account simultaneously the non‐linearity of the ferromagnetic parts by using a complete permeance network.
